Pull those hiking boots out of the closet, hunt your tent and sleeping bag down, and don’t forget your compass because this week, April 16-24th, is FREE National Park week! You read that right! Entrance to all 394 national parks is free entry, and if that isn’t enough for you, the National Parks app for smartphones (which is normally 4.99) will also be free of charge. This is one of those opportunities you’re not going to want to pass up!
